DESCRIPTION
The PCA9543 is a bi-directional translating switch, controlled by the
I2C bus. The SCL/SDA upstream pair fans out to two downstream
pairs, or channels. Any individual SCx/SDx channels or combination
of channels can be selected, determined by the contents of the
programmable control register. Two interrupt inputs, INT0 to INT3,
one for each of the downstream pairs, are provided. One interrupt
output INT, which acts as an AND of the two interrupt inputs, is
provided.
An active-LOW reset input allows the PCA9543 to recover from a
situation where one of the downstream I2C buses is stuck in a LOW
state. Pulling the RESET pin LOW resets the I2C state machine and
causes all the channels to be deselected, as does the internal power
on reset function.
The pass gates of the switches are constructed such that the VDD
pin can be used to limit the maximum high voltage which will be
passed by the PCA9543. This allows the use of different bus
voltages on each SCx/SDx pair, so that 1.8 V, 2.5 V, or 3.3 V parts
can communicate with 5 V parts without any additional protection.
External pull-up resistors pull the bus up to the desired voltage level
for each channel. All I/O pins are 5 V tolerant.
